Hydrophobic Millipore Express® SPG Gamma Stable Capsule Filters

Gamma Stable Opticap® XL Capsule Filters with Millipore Express® SPG (Sterile Phobic Gamma) hydrophobic membrane are the ultimate choice for optimal gas filtration and venting in single-use applications. The 0.2 μm sterilizing-grade membrane provides sterility assurance and high flow rates. Its ability to maintain flow rates during extended batch durations contributes to higher process confidence.

Features

The polyethersulfone membrane based gas filter:

• Can be sterilized by gamma irradiation or autoclaving
  
• Can be integrity tested using HydroCorr™ test
  
• Is validated for liquid bacterial retention
  
• Maintains superior flow rate over extended process duration

Typical Applications
